Issue:
We received a notification today that our Java process was taking more than 99% of CPU% usage.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
14043 root 20 0 4019m 2.5g 16m S 154.6 31.9 6034:33 java

Are you aware of any commands to run get some diagnostics off this? Or any other reasons why we would see this spike in CPU usage? I have attached the jboss logs for the server. please let me know if you need anything else.
Resolution:
Adding more CPU to the LB server resolved this issue.
